Diagnosis: Centrohelids with monolayered plate-scales covering the cell surface. Plate-scales with a hollow inflected margin. Sometimes, trumpet-shaped or tubular spine-scales are present, forming an outer layer of coverings. At some life-cycle stages the siliceous scales are completely overwritten with organic spicules with some intermediate stages having a combination of siliceous spicules and scales.
